These are pictures from a 1930 German article (which was linked on the dz.com German page.) Interestingly, the story uses the term "Taucher der Lüfte," which I guess can be loosely translated as "skydiver" -- the earliest use of this term I've found.

Interestingly, tod1 also appears in the book Nine Lives: the story of the parachutist John Tranum, opposite page 134. Most of the pictures have some sort of assignation as to where they came from, but that one does not.
